Helya Abilities & StrategyHelya

Phase 1 consists of fighting Helya directly, whilst dealing with Bilewater Slimes quickly before they annihilate the raid.

At 65% health phase 2 will begin and Helya will retreat away from the encounter area, players will have to deal with waves of various adds whilst destroying Helya's Gripping Tentacles that are scattered throughout the encounter area.

Once all Gripping Tentacles are destroyed, Helya will return and phase 3 will begin. Phase 3 mixes various abilities from phase 1 and 2 with slight mechanical changes to these abilities.

Phase 1: Low TideHelyaHelyaCorrosive NovaTaint of the Sea

Once it has been dispelled, it will deal a small amount of damage to the entire raid and spawn a Tainted Essence, which will then explode shortly afterwards, dealing a high amount of damage to anyone within 8 yards.

This debuff should be dispelled by the healers as soon as possible and then the player with the debuff and anyone nearby should move away from the Tainted Essence explosions left behind.

Do note that the tank who is tanking Helya is always targeted as one of the raid member to be hit by this ability, plan your movement ahead of time so you're not forced to move away from melee range.

Each orb will then fixate their player and chase after them for 8 seconds whilst pulsing out moderate aoe damage to anyone nearby.

If a player takes damage from the orb, they will take 100% extra damage from the next hit of the orb. This effect stacks.

Players should remain spread out when Orb of Corruption is due to come in to help minimize any accidental damage they might take.

The player fixated by the orb should kite it away from the group, towards the edges of the room.

The Orb of Corruption will always pick the off-tank and then random ranged players. The off-tank needs plan their movement so that they will be back within range of Helya by the time they need to taunt her Bilewater Breath.

HelyaBilewater BreathBilewater Slime

These adds are stationary and cannot be moved via grips, knockbacks or other displacement effects.

They will immediately begin to cast Bilewater Liquefaction. This 20 second cast will cause the Bilewater Slimes to explode and die, dealing a large amount of damage to the entire raid, reducing in damage by up to 80% based on the slime's remaining health.

The explosion will also create a pool of Bilewater Corrosion which lasts 45 seconds and deals ticking damage to anyone stood within. The size of the Bilewater Corrosion pool is also reduced by the remaining health of the Bilewater Slimes.

Bilewater SlimeBilewater Redox

Kill slimes fast... or you'll have large Bilewater Corrosion pools to deal with :(

It is more important that all adds take a large amount of damage, rather than having a couple of adds die whilst others are left on high health, as this will reduce the effects of Bilewater Liquefaction the most.

You may need to use healing cooldowns for each time the Bilewater Liquefaction goes off to help mitigate the damage of the ability.

However, if the raid manages to deal enough damage to the Bilewater Slimes this should not be necessary.

Shortly after spawning the tentacle will slam into the ground, inflicting a large amount of damage split between all players within its targeting area.

If the tentacle hits the ground and no player is within the targeting area, it cast Tentacle Slam which will deal a huge amount of damage to the entire raid, which in most cases is lethal.

It is important that you have as many people soak the Tentacle Strike as is convenient, to help split the damage between all players hit.

You are able to have a player use an immunity (Aspect of the Turtle/Ice Block) and then soak the tentacle strike by themselves. This helps reduce the damage taken by the raid substantially, whilst allowing players to spread out for abilities such as Taint of the Sea and Orb of Corruption.

If you have access to these immunities, we recommend using them on the Tentacle Strikes that occur at the back of the platform, as less members of the raid are going to be able to soak that without large downtimes in comparison to the tentacle that spawns at the front.

Bilewater SlimePhase 2: From the MistsHelyaGripping TentacleHelya

Each time a Gripping Tentacle is defeated, Helya will take a burst of damage equal to 2% of her maximum health.

Once all 9 tentacles have been killed, Helya will return to the platform, at 47% health, and phase 3 will begin.

You'll want to cleave onto these tentacles by tanking all adds that spawn on top of them, whenever safe.

HelyaTorrentTorrentHelyaBuilding StormTorrentTorrentHelyaFury of the Maw

This wave will remove any patches of Bilewater Liquefaction and Decay.

Each time Helya casts Fury of the Maw, she will buff herself with Raging Tempest. This increases the damage of Fury of the Maw by 25%.

As soon as you enter phase 2, one Fury of the Maw wave will travel across the room. The damage of this wave is low and therefore survivable.

However the next time Fury of the Maw is cast, multiple waves, empowered with Raging Tempest, will travel across the room in a row. The raid will need to avoid these waves by moving up onto one of the elevated platforms at either side of the room. During this time the raid wants to kill off any extra adds, whilst damaging the Gripping Tentacles that are on this elevated platform.

Fury of the MawFury of the MawNight Watch Mariner

Tank them near the Tentacles for maximum cleave! Dodge the Give No Quarter cast

Focus down the Night Watch Mariner first. Lantern of Darkness will be cast 25 seconds after he spawns. This will deal a large amount of ever increasing ticking damage to the entire raid every 0.5 seconds for 6 seconds. This ability is very likely to wipe the entire raid if cast in its entirety. Kill the Mariner before he has a chance to cast it.

Periodically the Night Watch Mariner casts Ghostly Rage, gaining 30% attack speed for 6 seconds. The tank should use active mitigation during this time.

The Night Watch Mariner will mark areas with Give No Quarter. A ghostly image of the Mariner will appear at the location of a ranged player, dealing a large amount of damage to anyone within 8 yards. You can avoid this ability by moving from the white swirly circle that spawns under the feet of the targeted player. Being pre-spread will help minimize overall raid movement whilst the Mariner is alive.

GrimelordSludge NovaFetid Rot

The Grimelord will deal a large amount of damage to the tank and anyone within the targeting circle around the tank when he casts Anchor Slam. These players will be knocked up and receive a debuff which increases all damage taken by 400% for 6 seconds.

Only the tank should be hit by this ability and should use a large damage reduction cooldown to survive it.

Alternatively, the other tank should taunt the Grimelord immediately after the cast, so the debuffed tank doesn't take any more damage.

Fetid RotGrimelord

This debuff deals light ticking damage every 3 seconds. The debuff originally has 3 stacks, and 1 stack will be removed every 3 seconds. Each stack will reduce healing taken by 10%.

Once the entire debuff is removed, the player will deal a burst of damage to any player within 5 yards, applying Fetid Rot to any player struck.

Players with this debuff must be spread at least 5 yards by the time the debuff drops to stop the Fetid Rot from spreading throughout the raid group. Healers should spot heal the players with the debuff to ensure they don't die from the damage aspect of the ability.

Night Watch MarinerGrimelordDecaying Minion

Each Decaying Minion will fixate on a random player with Rabid and run over and melee hit them.

Their melee attacks deal very little damage, however this damage ramps up over time as they periodically gain a stack of Vigor, which increases their damage done by 10% and this buff stacks up.

When the Decaying Minions die, they leave a large green patch of Decay on the ground which deals light ticking damage to anyone who stands within it. These Decay patches will be removed by the Fury of the Maw waves.

Decaying Minion

The Decaying Minions can be stunned, slowed and displaced through conventional means.

Grouping up these adds can be easier at certain points than others. When the raid needs to retreat up to the elevated platforms for the Fury of the Maw waves, the minions are easily funneled up the staircase and can be easily killed off.

However these adds can also spawn directly after a Fury of the Maw wave set. During that time the raid will need to manually stack the adds up to put them down.

Phase 3: Helheim's Last StandFury of the MawBloodlustHeroismHelyaCorrosive NovaTaint of the SeaNight Watch Mariner

Deal with him in the same way you did in phase 2. Tanks will still need to use active mitigation during ghostly rage and ranged players need to watch out for the Give No Quarter.

However you will need the DPS to put a lot more focus on him as he will cast Rally of the Kvaldir which increases his health by 100%, and you still need to kill him before he casts Lantern of Darkness.

Corrupted Breath

This breath deals a large amount of shadow damage to anyone within whilst applying Dark Hatred, which reduces all healing taken by a large amount.

Tanks should face the breath away from the raid and tank swap after each breath whilst the raid avoids taking the hit.

These orbs are similar, now they will leave patches of decay on the ground as they chase their fixated player.

It is important that the fixated targets kite the orbs around the sides of the room, whilst keeping the decay patches as stacked up as possible.

This decay will be removed when the Fury of the Maw wave travels across the platform, however these waves occur infrequently, so you must try and minimize the amount of space the decay patches take up.

Vigor

When they die they will leave a patch of Decay on the ground.

Killing these adds near or on top of one another helps maximize the amount of space you have in the encounter area. It is also important that they die before the Fury of the Maw cast, so that they Decay patches they leave behind are washed away.

Fury of the Maw

It is unreasonable to expect that players will have the time to travel to the elevated sections of the encounter area, and instead you will have to take the damage of the wave. Healing cooldowns can be used to compensate.

In the case that you decide to move to an elevated section of the encounter area, then it's important that a tank remains on the ground floor next to Helya to ensure that a Corrosive Nova doesn't go off.

Strategy SummaryPhase 1

Make sure a tank is always within melee range to counteract Corrosive Nova.

Be spread for when the Orb of Corruption is cast and have the fixated players kite the orbs away from the raid.

Quickly dispel the Taint of the Sea debuff and move out of the Tainted Essence it leaves on the ground.

Have the majority of the raid, or a single player with an immunity, soak the slam from the Tentacle Strike to avoid Tentacle Slam from wiping the raid.

Face Helya towards one side of the room for the Bilewater Breath, make sure that no Bilewater Slimes spawn on the elevated sections of the platform.

Have tanks switch who is tanking Helya after each Bilewater Breath.

Have all DPS focus down the Bilewater Slimes to reduce the severity of Bilewater Liquefaction.

Make sure no Bilewater Slimes are active before transitioning at 65% health.

Phase 2

Move as a single unit to an elevated platform during the Fury of the Maw waves.

Tank the Night Watch Mariner and Grimelord slightly apart from one another to allow melee DPS to focus down the Night Watch Mariner without having to move from the Grimelord's abilities.

Kill off the Night Watch Mariner before the Lantern of Darkness is cast, whilst having the tank use active mitigation during his Ghostly Rage. Ranged players should also move out of the Give No Quarter cast.

Move away from the Grimelord during his Sludge Nova and have the tank use large damage reductions for the Anchor Slam.

Move 5 yards away from your allies when Fetid Rot is going to time out, to prevent it from spreading to them.

Group up, crowd control and kill the Decaying Minions. Make sure they die on the lower sections of the room, so that the Decay they leave is washed away by the Fury of the Maw waves.

Kill off all 9 Gripping Tentacles spread around the edges of the encounter area to progress into phase 3.

Phase 3

Group up, crowd control and kill the Decaying Minions, make sure they die on the lower sections of the room so that the Decay they leave is washed away by a Fury of the Maw wave. It is also important they die close together so you can maximize the amount of room the raid has.

Kill off the Night Watch Mariner before the Lantern of Darkness is cast, whilst having the tank use active mitigation during his Ghostly Rage. Ranged player should also move out of the Give No Quarter cast.

Be spread for when the Orb of Corrosion is cast and have the fixated players kite the orbs around the edges of the room. Keep the patches of Decay they leave in their wake close together to maximise the room the raid has.

Use a healing cooldown when the Fury of the Maw wave washes across the encounter area. Alternatively, avoid the damage it deals by moving to an elevated platform.

Make sure a tank is always in melee range of Helya to prevent her from casting Corrosive Nova.

Face the Corrupted Breath away from the raid.

Tanks should switch after each Corrupted Breath to mitigate the effects of Dark Hatred.

Use Bloodlust/Timewarp/Heroism during this phase when dps cooldowns align.

Looking for Raid DifficultyHeroic DifficultyCorrupted BreathCorrupted Axion

When these bolts land they will each deal a large amount of damage to the raid and apply a large healing absorption shield on each player for 30 seconds.

If a player soaks the Corrupted Axion bolt, they will take the damage and healing absorption shield instead.

To counter this, you want to have the tank face Helya to one side of the room, whilst taking care to make sure that all bolts will land on the lower parts of the encounter area.

As soon as the breath has ended, players should enter that area and make sure that all Corrupted Axions are soaked. If this is not done, the combined damage of all Corrupted Axions will annihilate the raid.

Mythic Difficulty

The Orb of Corruption from phase 1 and the Orb of Corrosion from phase 3 will now have a Corrosive Slicer beam connecting them. Any player hit by the beam will take lethal damage.

The Fetid Rot in phase 2 will now attempt to spread each time a stack is removed, rather than at the end of the debuff. The Grimelord also has the ability to increase the number of stacks of Fetid Rot players have through Fetid Fission.

A new add is present in phase 2 & 3 called a Helarjar Mistwatcher. This add will attempt to empower Helya's Fury of the Maw ability via an interruptible spell called Mist Infusion. When this ability is interrupted, it will deal a burst of damage to the raid.

During phase 3, the Corrupted Axions from Corrupted Breath will now apply Corrupted to any player hit. These players will be mind controlled and can only be broken out by damaging them to 10% health.

If nightmare Mythic was done after 18 hours .. this one will be how much ? 4 hours ?

Comment by aaronmartin1651

When attempting to loot Helya her corpse bits are suspended in the air above water that kills you if you stand in it. Too high up to loot attempting to jump up to get it not only doesn't work but causes you to be in water long enough to die. Anyone else experience this?

Comment by QueenRaven29

You don't get The Chosen title from killing Helya on Mythic. You get the title for one shotting all of the bosses on mythic.

What's up with the Mythic part of this guide?... Any chance on some sort of tips to help out with the fight?

Comment by AveryZan

Just going to mention this for tanks out there dealing with the grimelord anchor smash. try to save a cd/ ask for externals on the anchor smash. I'm not entirely sure why but ever since they nurfed the fight I would occasionally get wreckt by that thing. On heroic mode with 30 players as a guardian druid with 2 stacks of armor mitigation I took a 5 mil swing. Using wall/ sleeper barkskin I only took about 1-2 mil. The party size was larger than what I normally did so maybe that had some impact, still seemed like a lot compared to tanking that ability before, have to wonder if there is a possible scaling bug. Other than that though the adds in general are far easier in p2 and makes the fight a whole lot easier.

Comment by Thechieftain

I would really like to read something about 5pack of tentacle soaking. Orb rotation. First on tank healer rdps second on mdps. Etc or tentacle spawn position.. For mythic i mean. More detailed would be great
